Abstract
This IP address distribution system is provided with a network formed from multiple switch devices (5, 6), IP address distribution devices (3, 4) which allocate IP addresses in response to requests from terminals (7-10) connected to the switch devices, and multiple position information distribution devices (1, 2) which broadcast, within the network, position information packets that include position information. By blocking position information packets in a specific physical port of one or more of the switch devices, only a single position information packet is distributed to each device. When requesting IP address allocation, a device sends an IP address request signal which contains position information and device-specific information, and when an IP address request signal is received, the IP address distribution device selects an IP address from a range corresponding to the position information and the device-specific information and distributes said IP address to the request-originating device.

Embodiment
Below, related IP address assignment system that present invention will be described in detail with reference to the accompanying and the execution mode of IP address assignment method.The present invention also can't help in fact to execute mode and limits.
Execution mode 1
Fig. 1 means the figure of structure example of the IP address assignment system of execution mode 1.It is switching device 5 and 6 and form that the IP address assignment system of present embodiment comprises positional information distributor 1 and 2, IP address assignment device 3 and 4, Ethernet (registered trade mark) switch.Positional information distributor 1 and IP address assignment device 3 are connected with switching device 5, and positional information distributor 2 and IP address assignment device 4 are connected with switching device 6.Switching device 5 is connected by the physical port 11 of switching device 5 and the physical port 12 of switching device 6 with switching device 6.
In addition, terminal 7 is connected with the physical port of switching device 5 with 8, and terminal 9 is connected with the physical port of switching device 6 with 10.In addition, terminal 7～10th, sends the request of assigning IP address the network equipment of accepting IP address assignment to IP address assignment device 3 or 4.Positional information distributor 1 represents to be present in the positional information of where (setting position of physical property) in network with 2 to the terminal distribution being connected with switching device 5 or 6.IP address assignment device 3 and 4 is preserved IP address assignment table (details will below set forth), when receiving the distribution request of IP address from terminal, according to IP address assignment table, assigns IP address.
The figure of the structure example of the positional information bag that Fig. 2 means in the IP address assignment system of execution mode 1, positional information distributor 1,2 sends during to terminal notice positional information.As shown in the figure, positional information bag has for storing respectively the region of sending destination address, transmission source address and positional information value.
Positional information distributor 1 and 2 moment in regulation send the positional information bag shown in Fig. 2 (for example periodically sending).Now, positional information distributor 1 and 2 is set for the multicast address of distribution locations information and is usingd as sending destination address, set the IP address of this device as transmission source address, and the value of the position of the terminal that set to represent to receive positional information bag in network is usingd as positional information value.In addition, positional information distributor 1 and 2 is set as positional information value by the intrinsic value of each position information distribution apparatus, and other positional information distributor can not repeated with the value set in positional information bag.
The action of switching device 5 and 6 (setting of physical port) is described.The bag that physical port 11 location information of switching device 5 divide the multicast address of adapted to be set to sending destination address is tackled.In other physical port, to sending destination address, be not or not positional information divides the bag of the multicast address of adapted to tackle.In addition the bag that, physical port 12 location information of switching device 6 divide the multicast address of adapted to be set to sending destination address is tackled.In other physical port, to sending destination address, be not or not positional information divides the bag of the multicast address of adapted to tackle.That is,, in switching device 5 and 6, in the physical port being connected with other switching device, the bag that location information divides the multicast address of adapted to be set to sending destination address is tackled.
Thus, the positional information bag sending from positional information distributor 1 is incoming terminal 7 and 8 only, and the positional information bag sending from positional information distributor 2 is incoming terminal 9 and 10 only.
Fig. 3 means in the IP address assignment system of execution mode 1, when terminal 7～10 request distributing IP address, is sent to the figure of structure example of the IP address request signal of IP address assignment device 3 or 4.As shown in the figure, IP address request signal has for storing respectively the area of sending destination address, transmission source address, positional information value and equipment intrinsic information.Multicast address and temporary ip address in sending destination address and transmission source address, have been set respectively.In positional information value, be set with the positional information value (with reference to Fig. 2) comprising the positional information bag that the equipment of transmission source receives from positional information distributor.In equipment intrinsic information, set the information (device category information) of the kind of the equipment that represents transmission source.For example, in the situation that terminal 7～10 is arranged on the equipment in railway car, by the device category information setting that represents guidance display, aircondition, brake apparatus etc. in equipment intrinsic information.In addition, suppose that each terminal preserved device category information in advance.
Here, the IP address assignment table of IP address assignment device being preserved describes.IP address assignment table means the information of the IP address that the combination of location information value and equipment intrinsic information (being device category information in present embodiment) distributes or the scope of the IP address of distributing, for example, be the information of structure as shown in Figure 4.IP address assignment device receives after IP address request signal, the positional information value of setting in the request signal receiving and equipment intrinsic information (device category information) are confirmed to the terminal by the corresponding IP address assignment of the combination with these information to request source.When preserving the IP address assignment device of the IP address assignment table shown in Fig. 4 and receive that for example positional information value is set as " 1 " and equipment intrinsic information is set as the IP address request signal of " A device ", " 192.168.1.1 " assigned as IP address.In addition, when receiving positional information value and be set as " 2 " and equipment intrinsic information and be set as the IP address request signal of " other ", in the IP address of selecting to comprise in the scope of " 192.168.2.3～192.168.2.254 ", do not divide the IP address of tasking any terminal to be used as IP address to assign.
Then, utilize the sequence chart of Fig. 5 to describe determining the step of the IP address of terminal in the IP address assignment system in present embodiment.As shown in the figure, positional information distributor 1 and 2 regular location information bags carry out multicast transmission.Now, because positional information bag can be tackled by the specific physical port of switching device (physical port that connects other switching device), so terminal 7～10 can be from a plurality of positional information distributor receiving position information bags.Terminal 7～10 receives after positional information bag, extracts positional information value from positional information bag.And, terminal 7～10 is assigned in request in the situation (not accepting the situation of IP address assignment) of IP address, by the positional information getting from positional information distributor 1 or 2, is that IP address request signal sends with the device category information setting of preserving in advance.IP address assignment device 3 and 4 receives after IP address request signal, the IP address that utilizes the IP address assignment table (with reference to Fig. 4) preserve to decide minute to task request source terminal, and the IP address assignment signal that comprises determined IP address information is sent to request source terminal.
In addition, IP address assignment device 3 and 4 is preserved identical IP address assignment table, when receiving in the situation of IP address request signal, with identical step, assigns IP address.That is,, when IP address assignment device 3 and 4 receives positional information value and the identical IP address request signal of device category information, assign identical IP address.Because terminal 7～10 can repeatedly receive the IP address assignment information of identical content from different IP address assignment devices, in the situation that the signal therefore formerly arriving is normally received, can ignore the signal of rear arrival.In addition, also can, in the situation that the IP address assignment signal repeatedly receiving has comprised identical IP address information, has been judged as and correctly carried out IP address assignment, and bring into use assigned IP address.
In addition, as the structure of the IP address assignment device in the IP address assignment system of present embodiment and the IP address assignment between terminal, also can make IP address assignment device bear the work of Dynamic Host Configuration Protocol server, make terminal bear the work of dhcp client.
As mentioned above, the IP address assignment system of present embodiment comprises positional information distributor, IP address assignment device and switching device and forms, positional information distributor represents the positional information of physics setting position to the terminal distribution of accepting IP address assignment, terminal is when request distributing IP address, transmission includes the positional information that gets from positional information distributor and the device kind of information of self at interior IP address request signal, and IP address assignment device is assigned the kind of the terminal with request source and the corresponding IP address of setting position.Thus, can with the physical routing of network on device location (setting position) distributing IP address accordingly.For example, though the equipment of accepting IP address assignment because failure and other reasons is changed, as long as discharge the IP address that is given to faulty equipment when changing or before changing, just can to the equipment after replacing give with exchange before the identical IP address of equipment.In addition,, even if do not discharge the IP address that is given to faulty equipment, also can give the IP address approaching with the IP address value that is given to the equipment before replacing to the equipment after changing.
In addition, the processing as discharging the IP address that has been given to faulty equipment, for example, can adopt as inferior method:, IP address assignment device with specified period to each equipment transmitted signal of giving IP address, inquire, if do not reply, discharge the IP address that is given to this equipment.
Can also adopt with the following method: IP address assignment device is after receiving IP address request signal, transmission using in the corresponding scope of additional configuration information, each IP address of having distributed is as the signal that sends address, whether inquiry unit (having given the equipment of IP address) exists, if there is unresponsive equipment, reallocated to the transmission source equipment of IP address request signal in the IP address that is given to this equipment.In this case, if there is equipment replacement, the IP address of giving the equipment before replacing can be given to the equipment after replacing reliably.
In addition, the physical port location information bag of switching device utilization regulation is tackled, make only by a positional information distributor, to send to the positional information bag of each terminal to arrive, therefore, can to the corresponding IP address of the actual setting position with terminal, assign reliably.
In addition, in present embodiment, to comprising that the IP address assignment system of two IP address assignment devices is illustrated, but in system, there is an IP address assignment device.
In addition, assumed position information distribution apparatus and IP address assignment device are that different devices is illustrated, but also can bring positional information distribution function and IP address assignment function into identical device, implement.

In addition, terminal 7 is connected with the physical port of switching device 20, and terminal 8 is connected with the physical port of switching device 21, and terminal 9 is connected with the physical port of switching device 22.
The different ports-settings that are in switching device of the IP address assignment system of present embodiment and the IP address assignment system of execution mode 1.Positional information distributor, IP address assignment device and terminal are carried out the action identical with execution mode 1, therefore omit action specification.
The action of switching device 20～22 (setting of physical port) is described.The physical port 23 of switching device 20 and the physical port 24 of switching device 21 make positional information divide the multicast address of adapted to pass through.On the other hand, the physical port 25 of switching device 21 and the physical port 26 of switching device 22 divide positional information the multicast address interception of adapted.
Thus, terminal 7 and 8 is only accepted the positional information bag sending from positional information distributor 1, and terminal 9 is only accepted the positional information bag sending from positional information distributor 2.
Based on condition as described above, at execution mode 2, also by the IP address deciding step identical with execution mode 1, decide the IP address of each terminal.; the specific physical port of switching device carrys out intercepting position packets of information according to the number of units of positional information distributor and setting position; only, from a positional information distributor to each terminal distribution positional information bag of accepting IP address assignment, therefore realized the IP address assignment system that can obtain with execution mode 1 same effect.
